A lick granuloma, also known as acral lick dermatitis, is a skin disorder in dogs. It results typically from the dog's urge to lick the lower portion of one of his or her legs. The lesion can initially be red, swollen, irritated, and bleeding, similar to a hot spot (wet eczema). The dog's incessant licking of the lesion eventually results in a thickened, firm, oval plaque. The most common cause of lick granuloma appears to be psychological, related to stress, anxiety, separation anxiety, boredom, or compulsiveness. Lick granulomas are especially seen in active dogs left alone for long periods of time. One theory is that excessive licking causes endorphin release, which reduces pain and makes the dog feel euphoric temporarily; that effect then causes an addiction to licking. Treatment of the primary cause, if known, is essential. In psychogenic cases, psychological factors should be identified and addressed, such as being left alone all day, being confined, and changes in the household. ==Symptoms== Lick granuloma is a form of self-trauma and skin disorder in which animals, particularly dogs, continuously lick a small area of their body until it becomes raw and inflamed. The most common areas affected are the lower (distal) portions of their legs, such as the carpus (wrist), or sometimes another part of their body such as the base of their tail. The lesion can initially be red, shiny, swollen, hairless, irritated, and bleeding, similar to a hot spot (wet eczema). Eventually a raised hard plaque forms. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lick granuloma」の詳細全文を読む スポンサード リンク
